The palace you see today is largely the work of the early eighteenth century. From 1721 to 1727, under Prince-Archbishop Franz Anton Harrach, Mirabell was rebuilt in lavish Baroque style, to plans by the architect Johann Lukas von Hildebrandt. The aim was to turn the earlier buildings into one grand, harmonious palace complex. Look for the court of the western wing, with its richly decorated facade. Its ground floor is rusticated, which means the stonework is given a rugged, textured look, and that expresses a Baroque idea of pastoral tranquillity. It is a lovely contrast with the ornament above. Inside, the star is the Donnerstiege, the stairway of Mirabell. It is a Baroque gem, with a generous helping of marble, sculpture and other artwork, and it is a unique piece in the heritage of Salzburg. Then there is the Marmorsaal, the Marble Hall, another elaborate expression of Baroque craft. It is celebrated today as one of the finest wedding halls in the world, and it is also a concert venue. This is the hall where the Salzburg Palace Concerts are held, and where, as the story goes, Leopold Mozart and his children Wolfgang and Nannerl once performed.
